1. Heads, intake, exhaust are all ok with speed density.bfox22 said:i am rebuilding a 5.0 and wanted have more power and do some mods to the engine like a cam and some injector and a intake. i understand that this won't work with speed denisty
Posted in another thread.But either way, do you see my point that when 1 cylinder is on its intake stroke, that injector fires, as does 3 other injectors. So that cylinder gets its mix, and the fuel that was sprayed into the other 3 cylinders just sits there. right? Now its onto the intake stroke of another piston. Repeat. Again, I know the cylinders can't steal from each other, but it just seems like if every cylinder only got a fuel shot when it needed it, a whole lot less gas would be wasted.
With MAF, one complete cycle of every cylinder means that 8 shots of fuel were fired.
With SD, you have 32 shots of fuel being fired. Only 8 of them being used for one complete cycle. So with the extra gas that sits in there, it obviously gets burned because it can't just fill up the intake manifold, so what does that do to the fuel mix if the computer is accounting for extra fuel in there, because wouldnt the hego see a rich mix? At WOT maybe it wouldn't make a whole lot of difference if the engine is spinning fast... but at cruise (1900rpm)?
